Question

briefly describe the manufacture of hydrogen from water gas. which is mixture of H2 an CO​

Answer 1

Answer:

Steam reforming is a hydrogen production process from natural gas. ... The process consists of heating the gas to between 700–1100 °C in the presence of steam and a nickel catalyst. The resulting endothermic reaction breaks up the methane molecules and forms carbon monoxide CO and hydrogen H2

CO + H2 , H2 + CH4 , CO + N2 + H2 , CO + H2O.

Answer 2

Answer:

The FID must be heated enough to prevent water formation; this is discussed in more detail in the section on detector temperature below. Since the flame is colourless and will not be seen in daylight conditions, the easiest way to confirm ignition is to hold a cold shiny object above the detector for a few seconds and observing the dew formation. A cold glass surface such as a beaker can also be used. Most instruments have some form of readout that will show a background signal when the flame is ignited. The FID can be used with any non-hydrocarbon carrier gas but will require small adjustments in flows to compensate for this. Carrier gas must be filtered to remove hydrocarbon impurities to reduce background signals. Make-up gas must also be hydrocarbon free. If the FID is used to measure trace hydrocarbons even the purity of the air is important and zero air should be used with appropriate in-line filters.

The FID has a linear dynamic range of about 107 which is often way above the range of the electronics and data system. Some manufacturers use automatic range switching to handle this shortcoming, otherwise the range must be adjusted to allow peaks of interest to be on scale. This would typically be peaks having a height of less than 1000 mV on most data systems. Heights greater than this will give flat top peaks whose areas are not representative of their true size.
